摘要
Six- and five-coordinate Fe(II) complexes with the pincer ligand 2,6-bis(imidazolylidene)pyridine (C-N-C), [(C-N-C) Fe(MeCN)(3)][BPh4](2) and [(C-N-C)FeBr2], respectively, were synthesized. Substitution of tmeda in [FeCl2(tmeda)](2) by C-N-C gave the six-coordinate {[Fe(C-N-C)(C-N-C*)][FeCl4]}, in which one of the pincer ligands is bound to the metal via the 2- and 5-imidazole carbons.
